An Abert's Squirrel Eating Sunflower Seeds

There is a black one hanging around with this gray one (courtship?)--and maybe that is the same black squirrel that I previously photographed.

Which brings me to the second oddity: All that I ever see in southern Colorado are black-phase Abert's squirrels, so this one's coloration is unusual for our area. Obviously the genes for the two-tone coat must be present in the black population.
